16
18 ldns_init_random() Seed the random function. If the file descriptor is
19 specified, the random generator is seeded with data from that
20 file. If not, /dev/urandom is used.
21
22 applications should call this if they need entropy data within
23 ldns If openSSL is available, it is automatically seeded from
24 /dev/urandom or /dev/random.
25
26 If you need more entropy, or have no openssl available, this
27 function MUST be called at the start of the program
28
29 If openssl *is* available, this function just adds more entropy
30
31 fd: a file providing entropy data for the seed
32 size: the number of bytes to use as entropy data. If this is 0,
33 only the minimal amount is taken (usually 4 bytes)
34 Returns 0 if seeding succeeds, 1 if it fails
